FRANCIS B. ALLDREDGE, OF DES MOINES, IOWA, ASSIGNOR T0 MILLS YB. ALLDREDGE, OF DES MOINES, IOWA.

SUPPLY-TANK AND CARBURETER FOR GAS PLANTS.

To all whom 'it may concern:

Be it known that I, FRANCIS B. ALLDREDGE, a citizen of the United States, residing in Des Moines, county of Polk, and State of Iowa, have invented a new and useful Improvement in Supply-Tanks and Carbureters for Gas Plants, of which the following is a specification.

The object of my invention is to provide a carbureter, or generator, for a gasolene machine in which a part of the gasolene is raised from the bottom, through the body of the gasolene, to the surface where it is there exposed for evaporation.

A further object is to introduce air into the volume of gasolene which is being raised from the bottom of the tank, prior to the time that it is exposed at the surface for evaporation, the air, obviously, traveling through the gasolene from the point where it is introduced, to the surface.

A further object is to provide a float for the surface of the gasolene in a carbureter tank, the said float being designed to contain the necessary means, or be of the necessary construction, to produce the above stated results.

A further object is to provide a means, in a carbureter of the class described, to securely lock the float in the bottom of the carbureter tank, for the purpose of transportation.

A further object is to provide such a device in a simple, strong, durable and practically inexpensive construction.

My invention consists of certain details of construction hereinafter set forth, pointed out in my claims and illustrated in the accompanying drawings in which Figure I shows a vertical sectional view of my carbureter complete; Fig. 11 shows a transverse sectional view of the same, taken at a point above the float; Fig. III shows a transverse sectional view of the float; Fig. IV shows a side elevation view of the float, a portion of the same being in section; and, Fig. V shows a detail view of the manner in which the float is locked in the bottom of the tank.

Referring to the accompanying drawings the reference numeral 10 is used to indicate the tank of the carbureter which is designed to be partially filled with gasolene, through Specification of Letters Patent.

the intake pipe 11 which may be located at any point in the upper part of the tank. The said tank is also provided with an out let pipe 12, through which the carbureted air is designed to pass to the mixer.

The float, which I employ, is comprised of a receptacle 13, of the construction shown in the drawings, and an air reservoir 14 secured within the receptacle, as shown, and held in position by means of the metal straps 15. As will be noted by reference to the drawings the tank, receptacle and reservoir are all circular in conformation and of the relative sizes shown.

The space between the reservoir and the receptacle, or the major portion of it, is filled by a tapering chamber 16, which in its central portion is very shallow and inclines gently upward on each side thereof, and around the reservoir, to a point nearly opposite where the ends of the chamber 16 are open, as is fully illustrated in the drawings. In the shallow part of this chamber 16 I have provided two intake pipes 17 and 18, the intake pipe 17 being secured to a flexible tube which extends downward therefrom to the base of the carbureter, and the intake pipe 18 being connected to a flexible tube which extends upwardly therefrom to a connection with an intake pipe 19. The tube secured to the intake pipe 17 is designed to convey the gasoline from the bottom of the tank 10 to the chamber 16, and as the said gasolene, being a liquid, will seek its .level it is obvious that it will completely flll the said chamber, flowing out of the two ends thereof into the open space 20, which exists between the reservoir and the receptacle 13, between the ends of the chamber 16.

From thence it will spread rearwardly and.

over the chamber '16. It is my purpose to admit air to the chamber 16, through the intake pipe 19, the tube and the pipe 18. It is obvious that as soon as the air is so introduced it will immediately seek to rise and the only manner in which this can be accomplished is by traveling through the upwardly inclined chamber, 16, to the outlet at 20, where it will be freed and it will there mingle with the carbureted air. The evaporatlng space consists of the space between the tank 10 and the receptacle and the space between the receptacle and the reservoir, for

it must be borne in mind that as the gasolene, rising through the tube from the bottom of the tank, flows through the chamber 16, it will be freed at the outer extremities of the said chamber and it will then flow back and cover the chamber, thus providing for the exposure of gasolene at all points between the reservoir and the receptacle. It is obvious that the float will rise and fall as the quantity of gasolene, in the tank 10, increases or decreases, and it is for this purpose that the tube connecting the pipes 18 and 19, and the tube depended from the pipe 17 are flexible. It is also my purpose to extend each of these tubes around the inner periphery of the tank, for a certain limited distance.

In the bottom of the tank I have secured, at two different points opposite to each other, one of the companion members, 21, of a hinged lock, and the other member for each of these is secured to the receptacle. These locks are for the purpose of securing the receptacle to the bottom of the tank, while the carbureter is being transported. The locking is effected by projecting a wire through the orifice, provided in each of the members on the receptacle, and through the orifices provided in their respective members secured to the bottom of the tank, the wires extending upwardly therefrom through the intake and outlet pipes, 11 and 12, respectively. IVhen it is desired to release the receptacle, so it may float on gasolene which has been introduced to the tank, it is only necessary to pull the wires out of the orifices in the members, 20 and 21, and upward through the aforesaid pipes.

In assembling the parts of my device together the air reservoir 1st is placed in position within the receptacle 13 and held in proper relation thereto by means of the metal straps 15. The chamber 16 is formed in the space between the receptacle and the air reservoir and is rigidly connected to the receptacle as shown in Fig. III. The flexible tubes are secured to the intake pipes 17 and 18 which are mounted in the shallow part of the chamber as shown in Fig. I. The cover of the tank 10 is not placed in position until the float has been secured therein, the wires projecting through the companion members of the hinges secured to the float and the base of the tank as hereinbefore described. The wires are then threaded through the intake pipe 11 and the outlet pipe 12 and the cover is then rigidly secured to the tank by any adequate means.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is:

1; A carbureter for gas plants comprising in combination a tank designed to contain gasolene; a receptacle designed to float on the surface of the gasolene; an air reservoir secured in said receptacle; a chamber between the receptacle and the reservoir, said chamber being provided with an outlet at each end and being inclined from its central portion to each outlet; means to admit gasolene to the shallow portion of said chamber; means to admit air to the shallow portion of said chamber, all arranged and combined substantially as shown and described.

2. In a carbureter for gas plants a float, designed to rest upon the surface of the gasolene, comprising in combination a receptacle open at its top; an air reservoir secured within said receptacle; a chamber in said receptacle, said chamber being shallow in its central portion and inclined upwardly toward each of the outer ends; a flexible tube extending from the base of the tank to the shallow portion of the chamber; a flexible tube extending from the shallow portion of the chamber to a connection to the outside of the tank, substantially as shown and described.

3. In a carbureter for gas plants a float, designed to rest upon the surface of the gasolene; a covering for the major portion of said float; a chamber within said float, said chamber being open at both extremities and being inclined upwardly from its central portion to each of said extremities; means to admit gasolene to the central portion of said chamber; means to admit air to the central portion of said chamber, substantially as shown and described.

4;. In a carburetor for gas plants comprising a tank, and a float to rest on the surface of the gasolene in the tank, a locking device to secure the float to the bottom of the tank, said locking device comprising members secured to the bottom of the tank and companion members secured to the float, all of said members being provided with orifices to receive wires; wires designed to bev projected through the orifices in their respective locking members, and extending upwardly there from through pipes to the outer surface of the tank, substantially as shown and described.
